BACKGROUND

The present disclosure is generally directed to a sanitation device and,more particularly, to a sanitation device that includes a source ofultraviolet (UV) radiation that is used to sanitize a surface.Additional embodiments of the present disclosure are directed to methodsof sanitizing surfaces using the device.

This disclosure further concerns sanitizing aircraft, particularlyaircraft cabins. Further the disclosure concerns sanitizing surfaces atand of locations associated with mass transportation.

The system applies, for instance, to airplanes, and other masstransportation systems, namely vehicles and collection and dischargeareas, and assembly locations relating for instance to buses, trains,ferries etc. and other forms of passenger conveyance.

A system and method trolley intended to sanitize the air and surfaces inan aircraft cabin that are commonly contacted by passengers in an effortto minimize the risk of disease spread.

Infectious disease transmission among air travelers is a significantpersonal and public health concern. Common and potentially serious viral(e.g. Influenza), bacterial (e.g. Methicillin Resistant Staph aureus),and fungal pathogens are typically spread through the air and frommutually contacted surfaces, known as “fomites”. Commercial aircraftcurrently use extensive on-board air filtration and ultraviolet “C” band(UVC) (extrinsic to cabin compartment) technologies to decrease airbornemicrobes, yet disease transmission continues, suggesting cabin surfacesmay play a role.

UVC is an effective germicidal technology not only for air, but forsurfaces. However, there is no currently available technology toeffectively and efficiently sanitize the surfaces of a passengeraircraft interior. The aircraft interior is never exposed to naturalultraviolet light. Chemical disinfection is labor intensive, withpotential harmful residues. Human exposure to UVC can be associated withskin and eye damage and care must be exercised in its use.

SUMMARY

The present disclosure generally relates to a sanitation device forsanitizing surfaces. In accordance with one embodiment of thedisclosure, the sanitization device includes a mobile body and a sourceof UV radiation. The source of UV radiation is mounted to the mobilebody, which is configured to travel over a surface. The source of UVradiation is configured to direct UV radiation to the surface at adosage sufficient to diminish microbial loads to acceptable levels.

Some distinguishing features of the current disclosure include:

-   -   a trolley for negotiating aircraft or similar aisles.    -   two arms, that are:        -   laden with UVC sources situated to disperse in a plurality            of directions        -   articulated to be laterally extensible over the seat backs            and retractable within the trolley footprint.        -   motor controlled and actuated.        -   variably extensible, depending upon the seating            configuration.        -   programmable, depending upon the seating configuration.        -   able to function independent of each other.

Yet another form is amodel remotely controlled by an operator standing nearby. For instancethere can also be an Pressure sensor; Ultrasonic sensor; HumiditySensor; Gas Sensor; PIR Motion Sensor; Acceleration sensor; orDisplacement sensor. Such applications could be in in differentenvironments, namely beyond an aircraft cabin. An application could bein in different environments, namely beyond an aircraft cabin.

Some different components of the system are set out:

1) Trolley

2) UVC source (lamp)

3) Trolley wheels

4) reflector

5) arm

6) arm extension retraction mechanism

7) rollers

8) hinges

9) guy wire

10) overhead bins

11) aircraft seats

12) light

13) vent

14) control

15) lavatory

16) galley

The trolley (1) has a “footprint” similar to that of a standardfood/beverage trolley used on aircraft, but is of substantially greaterheight. The trolley has wheels (3), at least one of which is connectedto a motor and at least one of which has a navigation mechanism. Themotor and navigation mechanism are connected to an on-boardmicroprocessor controller. There are proximity sensors, not illustrated,along the sides, fore and aft surfaces also connected to the controller.

Ultraviolet “C” (UVC) sources (2) are incorporated into all exteriorfore, aft and side, and bottom surfaces of the trolley and located in amanner to maximize exposure of the aircraft interior surfaces.Reflectors (4) are utilized to maximize effective UVC output.

UVC laden “arms” (5) are connected to the trolley in such a manner to bevariably laterally extensible above the aircraft seats (11) and belowthe overhead storage bins (10). These arms (5) may be retracted andstowed within the footprint of the trolley (1) for storage and whenmaneuvering the trolley (1) into position and on/off the aircraft. UVCsource lamps (2) are also located in a sufficiently elevated position toexpose the overhead storage bins (10).

Arms (5) may be configured in a variety of embodiments. FIGS. 1-4 showarms (5) essentially a folding frame containing UVC Sources (2) attachedto a scissors like extension/retraction mechanism (6). Theextension/retraction mechanism (6) may be attached to a linear actuator,not illustrated, and motor controlled by the microprocessor. FIGS. 5-8show an alternative arm embodiment wherein the UVC Sources (2) aredirectly embedded within the extension/retraction mechanism (6). FIGS.9-11 show a “roll-up” type arm embodiment with UVC sources (2) embeddedinto the extension/retraction mechanism (6). For clarity ofillustration, these arms (5) contain a limited number of UVC sources(2). Many more UVC sources (2) may be desirable depending upon thedesired dose of UVC exposure and other constraints.

These multiple embodiments are not intended to be all inclusive, butrather demonstrative of the myriad ways that this disclosure can beconstructed.

Vertical extensions with laterally directed UVC sources (2) also exposethe overhead bins. The height of these sources may vary, depending uponaircraft configuration.

Fans are also attached to the trolley (1) in such a manner to direct airflow into the path of UVC sources to sterilize the air. For example,fans directed laterally toward the floor can circulate air that mightotherwise remain relatively stagnant. UVC light also generates ozonefrom ambient oxygen which helps deodorize the cabin as an additionalbenefit.

Rechargeable batteries are located within the trolley to power themotor, controller, navigation mechanism, fans, arm extension mechanism,sensors, other electronics, and UVC sources. Some UVC lamps may alsorequire ballast. These heavier components are preferentially located atthe lower portion of the trolley to maximize lateral anti-tip-overstability. A power cord port, not illustrated, allows plug in chargingwhen the trolley is not in use. The batteries can be located within orattached to the trolley. In some forms, the batteries can snap on as anexterior battery pack, and the batteries can cooperate with a separatecharging station. In this way, the robot can be used to sanitize severalaircraft in succession by simply swapping the battery pack.

Operation

The trolley (1) is stowed off the aircraft, with arms (5) retracted, andplugged into an external power source to charge the on-board batteries.When ready for use, the apparatus of this disclosure is unplugged andwheeled onto the aircraft in a manner similar to known food/beveragetrolleys. The trolley is positioned in the aisle between the first row(or last row) of seats. The trolley is autonomously centered by sensorsand the navigation mechanism. Seats are detected by sensors orpreprogrammed by the number of rows, for example. The arms (5) areextended utilizing the extension/retraction (6) mechanism. The UVCsources (2) are powered on with a delay mechanism sufficient to allowpersonnel to leave the aircraft, or remotely. The trolley (1) proceedsalong the aisle, autonomously centered by the lateral proximity sensorsand the wheel (3) navigation mechanism. The apparatus of this disclosureproceeds autonomously to the last row (or first row) of seats, detectedby the aft proximity sensors or pre-programmed by the number of rows.The trolley (1) stops, reverses direction and proceeds in the oppositedirection in the aisle to the starting point.

The trolley (1) speed of travel may be programmed and is dependent uponthe UVC source output, distance from UVC source to surface, and desiredlevel of kill rate. Kill rates are dose dependent, measured in Wsec/m2and specific microbial sensitivities are known. The total treatmentduration should conform to other ground turn-around time constraints forthe aircraft.

When treatment is completed, the arms (5) are retracted to the stowedposition. The apparatus of this disclosure is then transported back tothe storage facility and plugged back into the external power source.

The device can be composed for instance, of three or more modules:

-   -   Cart—being the chassis, wheels, motors.    -   Base—which removably attaches to the Cart and is a covered        frame. Attached are lamps with reflective housings and a        telescoping mechanism. Electronics components fit within the        Base (e.g. controllers/processors, ballasts). Battery pack(s)        mount to the front and rear of the Base.    -   Wing Assembly—which fits into the Base with a telescoping        mechanism that allows vertical translation as described below.        The three modules fit together and electrical connections are        done via plug type connectors or wirelessly for signal transfer.

Advantages of this modularity include:

-   -   a) ease of manufacture    -   b) ease of transport    -   c) replacing a non-functional module rather than an entire unit.        Telescoping Wing Assembly

The Figures demonstrate the feature of the Wing Assembly that telescopesvertically into and out of the Base. This may be accomplished by avariety of known means including a track linear actuator, or a varietyof gears, pulleys, chains, belts, etc.

Advantages of this telescoping feature include:

-   -   a. ease of access into shorter aircraft doorways    -   b. markedly decreased tendency for tipping over    -   c. facilitating modal operation described below    -   d. accommodating a wider array of seating configurations        Some Alternative Embodiments

As shown in FIG. 22 there is a detailed view showing a Trolley with armstransversely extended and vertical support arms which are extendedvertically from the trolley and having horizontally extended fixed UVCelements which project UVC light from a higher level above the trolleybody trolley outwardly and transversely towards the area above theheight of the trolley body.

The extended arms can be seen in the undulating type relationship,wherein the support perimeters around the lights are a hinged supportwith the lights extending between the perimeter supports. There are twosets or banks of UVC light sets for each arm, and there are at least oneor two sets or banks of lights in side by side relationship such thatthere are at least three or four sets or banks of UVC lights on eacharm. These lights extend light both downwardly and upwardly from thearm. In the extended relationship the perimeter supports pivot about ahinge so that supports are upwardly directed at the center hinge. Withthis extended relationship, the light banks are pivoted downwardly asthe center about their central hinge.

Different Modes of Operation

In addition to sanitizing the passenger seating area, which may be aprimary source of germs, airlines and passengers are also concernedabout contamination of the lavatory and galley areas. The device mayfeature “modes of operation”, controlled via pre-programmedmicroprocessors, as indicated in the following table:

This is further illustrated and described with reference to FIGS. 29 to31.

WING LAMPS WING ASSEMBLY CART MODE POWERED DEPLOYMENT POSITION MOVEMENTSEATING All Both wings Up to seatback Along aisle at pre- AREA heightprogrammed rate of travel LAVATORY All Lamps on One wing into Primarilydown Stationary for pre- one side lavatory toward toilet, but programmedalso actively duration moving upward to expose countertop, sink, etc.GALLEY Outer lamps Both stowed Primarily down, Cart is turned 90 onstowed but also actively deg from aisle and wing and upward to exposemoves across lamps on countertop and width of galley at Base uppercabinets pre-programmed rate

The foregoing describes the minimum configuration of the currentdisclosure. A multitude of additions and variations are anticipatedbeyond this basic description. The following are representative examplesof alternative embodiments and additional features, but are not intendedto be all inclusive.

UVC sources may be fluorescent lamps, Light Emitting Diodes (LED),pulsed Xenon and other technologies known to produce ultraviolet lightin the germicidal range.

The trolley has an estimated weight of approximately 75 pounds. A motorassist for pushing the trolley may be incorporated to ease in itsmobility on and off the aircraft.

The UVC laden arms are foldable to substantially within the “footprint”of the trolley during transportation on and off the aircraft and forstowage. The arms extend substantially laterally and substantiallyperpendicular to the aisle at variable distance from the trolley. Thetwo arms extend laterally independently to accommodate asymmetricseating configurations. There are a multitude of known mechanisms thatallow this feature and some are illustrated within this application.More elaborate telescoping/folding/rolling or otherwise extensiblemechanisms can be incorporated into the design and the disclosureincludes such variations. The arms function independently of each otherto optimally treat aircraft that may have different numbers of seats oneach side of the aisle.

Because UVC light is potentially damaging to human skin and eyes, anonboard detection, warning and abort system is preferred. Sensors thatmonitor motion and heat or visual pattern recognition can beincorporated to detect human presence within a potentially dangerousradius of the device. Audible and visible alarms alert the human to thepotential danger. The device stops and the UVC sources are depowered toprevent possible injury. Similarly cameras can be included to remotelymonitor the trolley's progress. UVC does not penetrate clothing,plastics or glass and very simple personal protective gear covering allskin and a simple visor would allow a worker to be safely adjacent tothe trolley.

Programming may involve varying levels of automation. For example, onemay program for the cabin of a 777 aircraft and the controllerdetermines the direction, speed, number of rows, the desired extensionof the arms and height of the UVC sources for the overhead bins. Lesssophisticated programming may have variable row numbers, seats per row,speed of trolley travel, depending upon level of contamination etc.

A more sophisticated travel path may also be anticipated and programmed.For example, the arms may be programmed to follow the contours of thepassenger seat, going up and down around the seat backs and even down tothe floor to bring the UVC sources into closer proximity to contaminatedsources.

In the method, the device and apparatus is positioned to expose the UVsource in a positioned to expose the components of the aircraft desiredto be sanitized. There can also be a cleaning component with theapparatus and a waste container or tank with the device. The exposure ofthe cleaning component and the interior of the waste container or tankoperates to control the proliferation of microorganisms and thegeneration of odor.

The extensible arms have the ability to disinfect surfaces that are nottravelled over, but are remote from the travelled surface. Thosesurfaces, like seats, seat backs and tray tables cannot be travelledover and could not be sanitized are sanitized by the disclosed devicewhich has those extensible arms.

An alternative embodiment could have the arms going up and down betweenseatbacks as the device travels in the aisle to get the arms closer tothe sitting surface.

Surfaces like seats, seat backs and tray tables cannot be travelledover. Such surfaces could not be sanitized by a device that directs UVradiation to the surface on which it travels. The disclosed device, withextensible arms, allows such surfaces to be sanitized. The UV light alsohits vent control surfaces in an aircraft cabin. While UVC is directeddownward onto seats surfaces, a degree of UV is directed upward abovethe seats to sanitize the reading light (12), vent (13), and controls(14). This is to minimize the dispersion and existence of germs adherentto those surfaces. As seats, tray tables, armrests, etc. surfaces aretraveled over with the wing extensions, as stated, analogously, airvents, light controls, attendant call buttons are traversed fromunderneath as the robot travels with these wing extensions.

An alternative embodiment could have the arms going up and down betweenseatbacks as the device travels in the aisle to get the arms closer tothe seat surfaces.

An alternative embodiment is a permanent installation onboard anaircraft with a storage compartment. There can be a configuration of thedisclosure where the device would be stowed in a closed compartment andrather than wheels, for example a ceiling mounted rail system allows thedevice to travel fore and aft in the passenger compartment. An advantageto this system is that the aircraft can be sanitized regardless ofwhether the airport has functioning devices. A further advantage isapparent in case of an on-board inflight release of a pathogen, whetheraccidental/unintentional or bioterrorism. By activating an onboarddevice, with passengers shielded, an aircraft can be “sanitized”inflight prior to landing. This would avoid release of potentialpathogens at the destination and neutralize the threat prior to humaninoculation.

Intelligence/Programming for Seating Configuration

The device has a programmable microcontroller/processor that receivesinformation from the user and a multitude of on-board sensors. Thiscomponent controls the lamp power, wing deployment, and wing-assemblytelescope position and cart position/movement.

There are dozens of seating and cabin configurations in use withadditional configurations added annually. These include variations in:aisle widths, bends, floor surfaces; Seat widths, heights,reclinability, surfaces, row spacing; overhead bin and vent/lightcontrols; lavatory numbers, locations, fixture placements; galleylocations, countertop heights, and inserts.

Once an airliner's interior is configured, the device can be programmedspecific to that configuration and can be made to read the plane's tailnumber and know the configuration. Programs for different known aircraftconfigurations and for new aircraft configurations are implemented withthe device and method of usage of the device. These programs are tied toa sanitization device and a particular airplane. These programstransform a particular article into an airplane from un-sanitized to asanitized and germ cleaned device, namely from a viable germenvironment, area or surface to a dead germ environment, area orsurface.

A method and system of sanitizing seat surfaces in a location related toa public mass transportation vehicle includes a passenger area at thelocation. The area has multiple rows of seats arranged opposite to eachother with an aisle between the opposite rows. There are the steps of:

-   -   a) providing a sanitization device including a mobile body        configured to travel along the aisle of the passenger area of        the vehicle;    -   b) extending the sanitization device laterally from the mobile        body across a seat surface, a source of UV radiation being        mounted on the sanitization device;    -   c) moving the sanitization device across a first seat surface;    -   d) exposing the first seat surface to UV radiation produced by        the source;    -   e) moving the mobile body along the aisle while the device moves        over seats surfaces of subsequent seat rows;    -   f) directing a source of UV radiation to the seat surfaces at a        predetermined dosage while the device moves over seats surfaces;        the mobile body being powered by a power source on board the        mobile device;    -   g) programming a programmable microcontroller/processor for        receiving information from a user and a multitude of sensors on        the sanitizing device, the sensors being for accessing and        determining the relative location of the device in the        environment for sanitizing; and    -   h) having the processor control at least one of the radiation        power, the lateral deployment of the sanitizing device, a        vertical telescoping position of the sanitizing device and the        device position and movement device in the environment for        sanitizing.

The method and system is for sanitizing one of a designated aircraft.The aircraft has an aisle width, a bend, a floor surface plan, a seatwidth, a seat height, seat reclinability, seat surface character, seatrow spacing, overhead bin and vent/light control, lavatory number,lavatory location, fixture placement, galley location, countertopheight. A map of the aircraft is provided. The computer program inputsfor application to operate the sanitizing device at least onecharacteristic of the map being an aisle width, a bend, a floor surfaceplan, seat width, seat height, seat reclinability, seat surfacecharacter, seat row spacing, overhead bin and vent/light control,lavatory number, lavatory locations, fixture placement, galley location,countertop height. This provides a sanitizing device programmed tosanitize the designated aircraft.

The method and system can be for sanitizing one of a designatedaircraft. The aircraft has a designated plane tail number, and has thetail number relate to a configuration of the plane including providing amap of the aircraft. The device can be programmed specific to theconfiguration and reading the plane tail number to thereby apply theconfiguration to an operational program of the sanitization device.

As shown in FIGS. 30 and 31 there is shown the method and system for acontroller reading and accessing different planes: namely plane1, plane2and plane3. With the selected plane1, plane2 or plane3, the controllerthen configures the hardware and software of different features of thekind of plane including the different details of the floor map andfeatures of the seats and other plane map. This plane data is saved intothe database relating to the plane and the sanitizing device.

The controller then operates the computer hardware and software toprogram the sanitizing device, being selection of the type of plane,setting the device to operate, powering sanitizing device, beginningsanitizing, continuing sanitizing, ending sanitizing and finallyobtaining a sanitized plane. At this time the device is removed from theaircraft.

When used in a mass assembly area where there assemblies of people, thesystem can operate similarly and be programmed in the same manner. Inalternative form, there is a database check of the floor plan, and ifthere is not stored data about the floor plan the system is operatedmainly by an operator who walks behind or with the device and controlsthe device in manner similar to controlling a remote control car. Thisis illustrated in FIG. 32.

In some other forms of the disclosure the sanitizing device can driveautonomously in and about the mass assembly areas such as an aisle of aplane, a waiting area or room. In this manner the device is fitted withsensors for effecting navigation of the device over an area in a waysimilar to the navigation of a driverless car.

Different Power Alternatives

The sanitizing device and method is compatible with either battery poweror mains power. There can be a detachable battery pack and inverter thatattaches to the device and accommodates the 115 v plug. Alternatively,there can be a connector plug for plugged into a 115 v extension cord.

There are different applications of the method and system for sanitizingareas and surfaces. The method and system is for use on locations beingrelated to public mass transportation vehicles. As such, this can beused on buses, trains, ships, boats, ferries and waiting rooms and areaswhere passengers normally sit.

The system and method applies to areas of mass assembly or associationor congregation of people, public assembly areas and venues where thereare attendees.

Robots of the system and method sanitize theatres (live or movie),sports arenas and venues of public assembly. Although this disclosurerefers primarily to aircraft, the technology is applicable to all formsof mass transit and public areas as described. Such mass assembly areascould be selectively a mass transportation vehicle, a passenger area atthe location, or a venue for entertainment or sport.

Further although the disclosure relates to UV lighting, there can beother forms of lighting or radiation which are used which effectivelysanitize areas by applying the appropriate wavelengths and power levels.Further instead of the tubular format of dispersing the light there canother geometric and/or compact shapes of lighting source which are used,and for instance these could include appropriate LED lighting formats.

Many different formats are possible for the disclosure. It is thereforeto be understood that within the scope of the appended claims thedisclosure may be practiced otherwise than as specifically described.
